CHURN.

SZPEGIFICATION farming part of Letters Patent No. 307,111, dated Catcher28, 1884.

Applicanon filed March 1-], 18M.

To aZZ whom it may concern.-

Be it known that I, MICHAEL M. GREEN, a

citizen of the United States, residing at Shelby, in the county ofRichland and State of Ohio. have invented a new and useful Churn, ofwhich the following is aspecification, reference being had to theaccompanying drawings. I This invention has relation to churns; and itconsists in the construction and novel arrangement of parts, as will behereinafter fully described, and particularly pointed out in the claimshereto appended.

Figure 1 is a viewin perspective of a churn embodying the improvementsof my invention, a portion of the churn-body being broken away to showthe churndasher. Fig. 2 is a transverse vertical sectional vicw, andFig. 3 is a horizontal sectional view on the line a: x in Fig. 2.

Referring by letter to the accompanying drawings, adesignates the bodyof the churn, which is in the form of a tapering cylinder mounted on across frame, the projecting arms of which form feet for the churn-body,and steady it in its position during the operation of churning. Theinner face of the wall of the churn-body is provided with verticaltapering cleats b, triangular shape in cross-section, their basesresting on the bottom of the churn-body, and their points terminating adistance from the bottom equal to about two-thirds of the height of thechurnbody. The churnbody is provided on its outside near the mouth ofthe churn with a staple, c, at one side, and diametrically opposite thisstaple with another staple, c, and a short distance below the latterstaple with a third staple, c", which is aligned vertically with thestaple 0'. Each of these staples is provided with a thumb-screw, d, bywhich the frame that carries the mechanism for operating thechurn-dasher is removably secured to the churn-body. The lid is made intwo equal parts, the meeting edges being notched to form the centralopening forthe stem 6 of the churndasher, and is held in place bybuttons 0 on the inner faces of the arms f f of the frame g. The arms ff of the frame 9 are slightly curved inwardly near their upper ends, andare con nected about midway of their length byacrossbar, 72, having avertical central opening, 6, in-

(No model/l tersected by lateral perforations k entering from oppositeedges of the cross-bar h, which form seats for the guidc-pins'l Z, thepoints of which enter the groove mof the screw portion a of thedasher-stem, fora purpose herein after explained. These arms ff arefurther connected a short distance below their upper ends by a bowedmetal cross-bar, 0, having a central laterallyprojecting arm, 0,extending inwardly from said bowed arm between the armsff. This arm 0 isprovided withavertical perforation near its unsecured end to receive andguide the small upper end of the sectional dasherstein, and may bemetal-faced on its edges to give it additional strength. The upper endsof the armsf f are provided with bearings 12 p for the journals of thebent crank-shaft p, which is provided with a crankarni, p bent at anangle of about ninety degrees to the bend of the "crank-shaft. The lowerends of the armsf f are provided with shoulders q (1 on their innerfaces, formed. by reducing the thickness of the arms, to cause them tofit into their respective staples, the shoulders resting on the edge ofthe churnbody when the frame is in place, the thumbscrews beingtightenedto hold it, and the lidsections notched to receive said arms. The armfis longer than the arm f, and its lower end is secured in the lowerstaple, o this being the crank side of the frame, to give greaterstability to the frame. The upper end-of the screw-section a isprovided. with a collar, 1', rigidly secured thereon, and from whichextend short lateral arms 1* 1", which have their hearings in the lowerends of the arms 8 s of the bifurcated pitman 3, connected at its upperend by a loop or eye connection, t, to the middle straight portion ofthebent crank-shaft. The lower end of the screw portion a of the dasherstem is provided with a couplingsocket, it, having a thumb-screw, u, thepoint of which engages the metal-incased upper end of the dasherstemproper, 16 (when the latter is inserted into the socket,) and the screwit turned up to holdthe stem-sections together. The lower portion of thedasher-stem is enlarged and is cylindrical in form, and forms the middleportion of the dasher. To thelower end of the cylindrical portion 22 aresecured the crossed fiat heaters o 1). They are in the form of a Romancross, and near their ends are pro vided with groups of Verticalperforations, five in each group, arranged as shown. The cylindricalportion o is provided with four diametrical horizontal perforations,arranged one above the other at shortintervals of space, in which aresecured four small wooden rods or arms, w, which extend outwardly fromthe portion 2), and on the ends of these rods are secured twolaterally-perforated vertical heaters, 00 00, which are nearlywedge-shaped in cross section, the head of the wedge or inner edge ofthe vertical beaters being bored to receive the ends of the wooden rods.

The operation of the churn is very simple, yet the best results havebeen attained by it. lVhen the crank is operated, the crank-shaftrevolves and carries with it the bifurcated pitman, which, beingconnected to the arms of the collar secured to the dasher-stem above thescrew portion n, lifts the dasher-stem and forces it down again at everyrevolution of the crank-shaft. This movement of the crankshaft imparts avertically-reciprocating motion to the dasher, and at the same time theguidepins in the groove of the screw portion it cause the screw portionto make a horizontal halfrevolution forward during the upward motion ofthe screw, and a horizontal half-revolution backward to its firstposition when the screw moves downward, so that the churn-dasher hasboth a vertical reciprocating motion and a horizontal rocking motion.

It has been found by actual trial in competing with other churns thatthis churn will cause the butter to come quicker than any churn withwhich it has been placed in competition. It does not matter in whichdirection the crank is turned,the motion of the dasher will be the same.The parts can be readily and quickly disconnected when it is necessaryto clean the churn. The butter is gathered on opposite sides of thedasher.

This churn possesses simplicity, durability, cheapness, and generalefficiency.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. In a churn, the combination, with the body thereof having theinternal vertical pointed tapering cleats extending upward from thebottom of the churn,of the dasher-stem enlarged at its lower end andhaving the perforated horizontal beaters v v, secured thereto andarranged in the form of a cross, lateral rods passing through theenlargement, the per- ,forated vertical heaters secured to the ends ofthe rods above the horizontal beaters, and mechanism for imparting tothe dasher thus formed a vertical reciprocating and a horizontal.rocking motion, as set forth.

2. In a churn, the combination, with the I churn-body having a frameremovably secured thereto, and comprising a central cross-bar, 71connecting upright side bars, ff, and abowed or curved frame, 0,provided with the projecting guide-arm 0, which is perforatedvertically, as shown, of the dasher-stem 6, provided with acoupling-socket, a, to connect it with the screw portion a,thelatterpassing through the opening in the cross-bar, a collar, 0', atthe upper end of the screw portion, apitman provided with arms 8 8,attached to the collar at their lower ends, and the bent crank-shaft 1),having an OperatinghandIe, and connecting In testimonythat I claim theforegoing as inyown I have hereto affixed my signature in presence oftwo witnesses.
